The Sound of Music, set in pre-WWII Austria, is based on the romantic true story of Maria von Trapp, an aspiring nun who leaves the abbey to become a governess for the widower Captain von Trapp's seven children and finds herself falling in love with her employer and questioning her religious calling. It premiered on Broadway in 1959, where it broke box-office records and won the Tony Award for Best Musical. The 1965 film version won the Best Picture Oscar. Today it is an evergreen classic - as popular in opera houses and outdoor amphitheaters as it is in high school auditoriums. The Sound of Music features a libretto by Howard Lindsay & Russel Crouse and a score by Richard Rodgers (music) and Oscar Hammerstein II (lyrics) that includes "My Favorite Things," "Do-Re-Mi," "Edelweiss," and "So Long, Farewell."

Underwood’s 2005 debut, “Some Hearts,” topped Billboard’s Country Albums chart for 27 weeks, has sold over seven million copies, and was voted #1 Country Album of the Decade by Billboard. Her 2007 sophomore album, “Carnival Ride,” 2009’s “Play On,” and her current album, “Blown Away,” debuted atop the all-genre Billboard 200 chart. Over the course of four albums, she’s saturated country radio with such #1 hits as “Jesus, Take the Wheel,” “Before He Cheats,” “So Small,” “Last Name,” “Cowboy Casanova,” “Good Girl” and “Blown Away.” Underwood is currently headlining “The Blown Away Tour,” performing internationally and in arenas across the U.S. and Canada well into 2013. She was the top-selling country female touring artist of 2008 and 2010, as her headline arena tours have played over 100 shows and to over one million fans each year.

Underwood expanded her resume making her film-acting debut in the 2011 feature “Soul Surfer,” following a guest TV role on “How I Met Your Mother.” She starred in her own holiday variety TV special in 2009, and has co-hosted the Country Music Awards for the past five years. Underwood is managed by XIX Entertainment and repped by CAA.
